Below the straight valve sleeve, the lower end of the first guide rod abuts against the upper end face of the valve column, and the isolation column is located above the vertical sleeve.

The specific work of the municipal road drainage structure with emergency drainage function of the present embodiment is as follows:

The accumulated water on the road is discharged into the drainage pipe through the sewer, the vertical diversion pipe and the sewer connection pipe, and then drained away by the drainage pipe; in this process, the rainwater grate performs the first filtration to filter out the larger garbage, and the vertical guide The filter device in the flow pipe performs a second filter to prevent fallen leaves, plastic bags and other garbage from entering the drainage pipe, thereby effectively avoiding the blockage of the drainage pipe, resulting in excessive water accumulation on the road, which seriously affects the normal use of the road surface.

During the working process of the filter screen device, when the conical filter screen is blocked by garbage, the pressure of the water above the conical filter screen will overcome the elastic force of the return spring of the vertical sleeve, so that the sliding sleeve will move down until the sliding sleeve At this time: the vertical sleeve extends into the vertical valve sleeve, the lower end of the vertical sleeve touches the upper end surface of the piston body, and the passage between the piston body and the sleeve is located at the vertical valve sleeve. The bottom of the sleeve, and the lower end of the first guide rod is against the upper end face of the valve column, so that the spacer column is located above the vertical sleeve.

When the isolation column is located above the vertical sleeve, the water accumulated above the conical filter screen will be discharged into the garbage collection tank through the vertical sleeve, the sleeve outlet, the vertical cleaning pipe and the collection pipe. During the process, the water flow will drive the garbage attached to the conical filter to flow into the garbage collection tank together, thereby automatically cleaning up the garbage on the conical filter.

When the garbage on the conical filter net is cleaned, under the action of the return spring of the vertical sleeve, the sliding sleeve moves upward and resets until the sliding sleeve touches the upper limit block of the pipeline; at the same time, under the action of the return spring of the piston body Down, the piston body is driven to move up into the vertical valve sleeve, and the vertical valve sleeve is blocked.

After the rubbish on the conical filter screen was cleaned up, the accumulated water on the road surface was discharged into the drainage pipe through the gutter, the vertical flow guide pipe and the water connection pipe again, and was drained away by the drainage pipe.

The garbage and water flowing into the garbage collection tank will be discharged into the drainage pipe through the drainage outlet of the collection tank and the auxiliary connecting pipe, and will be drained away by the drainage pipe; the garbage will be collected in the garbage collection tank, and the operator will open the seal The end cover regularly cleans up the garbage in the garbage collection tank.

On the other hand, when the conical filter screen is blocked by garbage (that is, the vertical diversion pipe is blocked), if the rainwater is large, the water in the sink can also be discharged into the drain pipe through the emergency drain pipe to avoid the flow caused by diversion. The pipes are blocked, causing too much water on the road, which seriously affects the normal use of the road surface.
